Instructions
Preheat oven to 375°.
Butter a 9 x 5 loaf pan and set aside. You can use a little of the melted butter to do this. Just pour a little in the pan and grease the pan.
In a large mixing bowl, stir the flour, brown sugar, baking powder, and salt. Combine well.
Add half of the melted butter and the club soda. Mix until just combined with a spatula. Batter will be lumpy and dense.
Pour into the prepared loaf pan and even out with the spatula. I don't like to smooth the top because those uneven little bumps make an incredible crunchy topping.
Pour the remaining melted butter on top. If you want to ensure no butter oozes out onto your oven floor, you can line a baking sheet with foil and place the pan on the baking sheet.
Bake for 1 hour.
Turn out the bread on a cooling rack and let cool.
Serve plain, with butter, or whatever else trips your fancy.
